Market parking sensors are devices that assist drivers while reversing and parking. They use ultrasonic or electromagnetic technology to detect obstacles and provide audible or visual alerts. These sensors improve safety and convenience by minimizing blind spots and helping park in tight spaces. There are two main types of market parking sensors:
Market parking sensors have different specifications that determine their functionality. Here are some of them:
Detection Range
Market parking sensors have different detection ranges depending on the model and type. The range is usually between 0.2 to 2.5 meters. A sensor with a long range has a wider detection area. It can pick large and more distant objects. On the other hand, sensors with short detection ranges are effective in close interactions.
Number of Sensors
Some parking sensor systems have a single sensor, while others have up to 8 sensors. More sensors provide better coverage. They also enhance detection accuracy by offering a comprehensive view of the surroundings.
Operating Frequency
Market parking sensors use different frequencies to minimize interference. The commonly used frequency is between 40 kHz to 200 kHz. A higher frequency provides better resolution. It can detect smaller objects. Lower frequencies have a longer range and are more effective in detecting larger objects.
Voltage Supply
Most market parking sensors operate on the vehicle's 12V electrical system. They also have voltage supply variations of about ±2V. This variation ensures the sensors operate optimally. They prevent damage from voltage fluctuations.
Field of View
Different parking sensors have different fields of view. It is usually between 90° to 180°. A wider field of view enables the sensor to detect objects over a broad area. However, it can compromise detection accuracy by causing false positives from unrelated objects within the extended range.
Temperature Range
Market parking sensors are designed to operate in various environmental conditions. They have an operating temperature of between -40°C to 85°C. This ensures the sensors function optimally, regardless of the ambient conditions.
Market parking sensors require regular maintenance to function optimally and improve longevity. Here are some of the maintenance requirements:
It is important to check the sensor housing and wiring for any signs of damage or wear. Users should inspect the parking sensor systems regularly for loose connections or moisture ingression.
The sensors should be cleaned regularly to remove dust, dirt, or debris. Users should use a soft cloth and mild detergent to prevent interference with their ultrasonic signals.
Market parking sensor systems are prone to moisture damage. Users should apply moisture-resistant coatings and sealants. They should also ensure the sensors are well protected from water exposure.
Some advanced parking sensors require regular firmware updates. Users should follow the manufacturer's instructions and use the relevant tools for the updates.
The sensors should be calibrated periodically to maintain accuracy. Users should follow the manufacturer's instructions for the calibration process.
The market parking sensors are affected by extreme weather conditions. This includes high temperatures or heavy rainfall. Users should install the sensors in a protected area to minimize the exposure risks.
When buying a parking sensor for a market, businesses should consider their customers' needs. They should check every feature that could affect the sensor's performance and reliability.
System type
Both the visual and audible alert systems have their perks. The choice depends on the user's preference. Consider the type of alert that would suit the target customers better.
Sensor coverage
The more sensors a parking sensor system has, the more coverage it offers. A six-sensor system provides better coverage than a four-sensor system. However, it may also be pricier. Consider the sensor number that provides the best value for money.
Detection range
Both ultrasonic and electromagnetic parking sensors have different detection ranges. Ultrasonic sensors can detect objects up to 6 feet away. If a market has huge objects to park, it would be best to go for electromagnetic sensors. They can detect objects up to 12 feet away.
Installation
Wireless sensors are very easy to install. They are ideal for markets that want to avoid the costs of hiring professional installers. If a market is on a budget, it could choose the parking sensors that are easy to install.
Features
Advanced market parking sensors come with more helpful features. These include a rearview camera, an LCD screen, and a voice alert system. They help provide drivers with a more comfortable and safer parking experience. Consider whether the market needs sensors with such extra features.
It is important to always read the installation manual that comes with parking sensor kits. The manual will give detailed instructions on how to install a specific sensor, as different models may vary in installation.
Generally, here are some steps to follow:
Prepare the Vehicle
Clean the area where the sensors will be installed. This is usually the back bumper for reverse sensors or the front bumper for front sensors. Also, remove any accessories or parts that may interfere with installing the sensors.
Check the Sensor Kit
Ensure that all components are available. This includes the sensors, control unit, wiring harness, display or speaker (if applicable), and mounting hardware. Also, make sure that the sensors are functional by testing them as instructed by the manufacturer.
Determine Sensor Placement
Decide where to place the sensors according to the manual's instructions. Generally, they should be evenly spaced and placed at a safe distance from the vehicle's edges.
Install the Sensors
Drill holes in the bumper for sensor installation. The holes should be the same size as the sensor casings. After that, insert the sensors into the holes and secure them with the provided mounting hardware. Also, connect the sensors to the control unit using the supplied wiring harness.
Connect the Control Unit
Market parking sensors have a control unit that processes data from the sensors. Install the control unit according to the manufacturer's instructions. Connect it to the vehicle's electrical system to ensure it gets power. Also, connect the control unit to the vehicle's reverse light circuit. This will activate the sensors when the vehicle is in reverse.
Test the System
After installing the sensors, perform a system test to ensure everything works. Check the display or listen to the audible warnings to ensure they accurately reflect the surroundings.
Reassemble the Vehicle
Once the parking sensor system is working correctly, reinstall any removed parts or accessories. Ensure everything is properly secured and functioning.
Final Check
Do a final check to ensure the sensors are correctly aligned and the system is working as expected. Take the vehicle for a test drive to confirm the sensors function properly in real-world conditions.
Q1: Where is the market parking sensor placed?
A1: The market parking sensor is usually placed on the rear bumper of vehicles. Some models may be installed in the front bumpers. They are installed at a height that can detect obstacles that are close to the vehicle when it is reversing or driving slowly.
Q2: Do parking sensors work through a trailer?
A2: In most cases, parking sensors can penetrate objects like trailers. However, their effectiveness may be reduced, and they may give false alerts or be less sensitive when detecting nearby objects. This is because trailers can obstruct sensors' clear view of the surroundings.
Q3: How do market parking sensors work?
A3: Parking sensors detect obstacles using ultrasonic or electromagnetic waves. They emit sound waves and listen for echoes. If there is an obstacle, the waves reflect back, and the sensor processes the signal. The system then warns the driver through visual cues or audible tones, depending on the proximity of the obstacle.
Q4: Can parking sensors be installed on any vehicle?
A4: Yes, parking sensors can be installed on any vehicle. Even though they are mostly found on high-end and modern vehicles, aftermarket sensors are accessible and can be installed on cars, trucks, and even motorcycles, improving safety and convenience while parking.
Q5: Can market parking sensors be installed on a trailer?
A5: Yes, parking sensors can be installed on a trailer. Trailer sensors can be installed on the rear and front ends of the trailers, improving awareness of the surroundings and making parking and maneuvering easier and safer.
